Descriptive data from Isaacs-Kidd midwater trawls (IKMT) from NH1106, Guaymas Basin. Dataset Description: <p>Sampling locations, depths, times, etc. from midwater trawls performed on the NH1106 cruise in the Guaymas Basin. Samples are archived in the biocuration facility at Oregon State University.</p> Methods and Sampling: <p>Tows with a 2m x 2m Isaacs-Kidd Midwater trawl (IKMT), 7m in length, with a 1mm mesh were conducted periodically throughout the cruise. The net was fitted with a Simrad PI depth sensor that provides net depth information in real time acoustically. Trawls were targeted to depths of interest based on acoustic sampling with the goal of achieving 20 minutes of towing time at the target depth at a target speed of 4 knots. Samples were preserved in 5% buffered formalin in seawater and are archived in the biocuration facility at Oregon State University.</p>

Hypoxia and the ecology, behavior and physiology of jumbo squid, Dosidicus gigas

Hypoxia and the ecology, behavior and physiology of jumbo squid, Dosidicus gigas
<p>This project concerns the ecological physiology of<em> Dosidicus gigas</em>, a large squid endemic to the eastern Pacific where it inhabits both open ocean and continental shelf environments. Questions to be addressed include:<br />
1) How does utilization of the OML by <em>D. gigas</em> vary on both a daily and seasonal basis, and how do the vertical distributions of the OML and its associated fauna vary?<br />
2) What behaviors of squid are impaired by conditions found in the OML, and how are impairments compensated to minimize costs of utilizing this environment? and<br />
3) What are the physiological and biochemical processes by which squid maintain swimming activity at such remarkable levels under low oxygen conditions?</p>
<p>The investigators will use an integrated approach involving oceanographic, acoustic, electronic tagging, physiological and biochemical methods. <em>D. gigas</em> provides a trophic connection between small, midwater organisms and top vertebrate predators, and daily vertical migrations between near-surface waters and a deep, low-oxygen environment (OML) characterize normal behavior of adult squid. Electronic tagging has shown that this squid can remain active for extended periods in the cold, hypoxic conditions of the upper OML. Laboratory studies have demonstrated suppression of aerobic metabolism during a cold, hypoxic challenge, but anaerobic metabolism does not appear to account for the level of activity maintained. Utilization of the OML in the wild may permit daytime foraging on midwater organisms. Foraging also occurs near the surface at night, and Dosidicus may thus be able to feed continuously. <em>D. gigas</em> is present in different regions of the Guaymas Basin on a predicable year-round basis, allowing changes in squid distribution to be related to changing oceanographic features on a variety time scales.</p>
<p>This research is of broad interest because <em>Dosidicus gigas</em> has substantially extended its range over the last decade, and foraging on commercially important finfish in invaded areas off California and Chile has been reported. In addition, the OML has expanded during the last several decades, mostly vertically by shoaling, including in the Gulf of Alaska, the Southern California Bight and several productive regions of tropical oceans, and a variety of ecological impacts will almost certainly accompany changes in the OML. Moreover,<em> D. gigas</em> currently supports the world's largest squid fishery, and this study will provide acoustic methods for reliable biomass estimates, with implications for fisheries management in Mexico and elsewhere.</p>
